参考答案与解析
一、单项选择。
1. D
【解析】句意：我们推荐大卫为今年的最佳歌手，因为他的嗓音很好听。
考查名词辨析。noise噪音；sound声音，泛指一切声音；shout呼喊、叫喊；voice嗓音。根据“We recommended David as this year’s Best Singer”推荐大卫为今年的最佳歌手，可知应是因为他的嗓音很好听，故选D。
2. D
【解析】句意：很多事情都会影响我们的情绪，比如颜色、天气等等。
考查动词辨析。cause引起；protect保护；improve提高；affect影响。根据“Many things can ... our moods”结合选项可知，affect最符合语境，表示很多事情可以影响心情。故选D。
3. C
【解析】句意：——你在做什么？——我正在为一份报告准备笔记。
考查现在进行时。结合语境和问句可知，答句用现在进行时表示现在正在做的动作。故选C。
4. B
【解析】句意：——为什么保护区如此重要？——因为它们可以为野生动物提供食物和住所。
考查动词辨析。practice练习；provide提供；prepare准备；protect保护。根据句意及空后“with food and cover”可知，此处是provide sb. with sth.，意为“为某人提供某物”。“provide wildlife with food and cover”为野生动物提供食物和住所。故选B。
5. B
【解析】句意：近些年来，我们国家的经济飞速发展。
考查动词时态。句中的in recent years 意为“近些年来”，是现在完成时的时间状语，又因为主语the economy of our country是第三人称单数，故选B。
6. A
【解析】句意：托尼的妈妈看起来年轻漂亮。很难想象她已经50多岁了。
考查数词用法。fifty；五十；fiftieth第五十。根据语境可知，本题考查in one’s fifties在某人50多岁的时候，故选A。
7. B
【解析】句意：——你认为这里的环境怎么样？ ——非常好啊！有五分之二的陆地都被绿植覆盖。
考查分数的表达。分数的表达口诀：子基母序，分子大于一，分母加s。具体解释：分子用基数词，分母用序数词，当分子大于1的时候，分母要加s。所以根据表达规则，正确的选项只有Two fifths, 故选B。
8. D
【解析】句意：合肥大约有800万人口。这意味着合肥人口众多。
考查数词。million百万，数词+million表示“几百万”；millions of表示“成百万上千万的”，排除A和C，large形容人口多；huge形容人口多；big形容人口多；small形容人口少，主语是“the population of Hefei”，由语境可知，应该是人口多，排除B，故选D。
9. A
【解析】句意：Lily取得了如此快的进步以至于她的老师在全班面前表扬了她。
考查形容词辨析。rapid快速的；huge巨大的；perfect完美的；bright明亮的。根据句意可知，C和D两个修饰词意思不合适；huge一般指体积、容量大，修饰progress不合适。故选A。
10. B
【解析】
句意：——请问我可以找一下Jim吗？——请不要挂电话，我看看他是否在家。
Keep on继续；Hold on别挂电话；Put on穿上；No不。根据对话的意思可知，这是两个人在打电话，根据I will see if he is in可知应选B。
二、句型转换。

三、用所给单词的正确形式填空。
16. preparing
【解析】句意：学生们正在预习他们的功课。结合语境和横线前的be动词“are”可知，此句强调此刻正在进行的动作，时态应用现在进行时，所以此空应填动词prepare的现在分词形式preparing。故填preparing。
17. fifth
【解析】句意：他们下周将在学校举行第五次运动会。根据“the ... (five) sports meeting”可知空后是单数，表示第五次运动会，用five的序数词fifth表示“第五”。故填fifth。

22. carefully

23. noisy, noise
【解析】句意：这间教室非常吵闹，因为许多男孩制造了这么多噪音。noise噪音，是名词，noisy喧嚣的，吵闹的，是形容词，第一空作为系动词is的表语，有副词very修饰，用形容词；第二空有形容词much修饰，用不可数名词，故填noisy, noise。
